Figure 18 is aside elevation of a portion of the side ring shown in Figures 14 and 17.

Figure 19 is an enlarged hub detail.

In the drawing l indicates the hub of the wheel, which is here shown as adapted to fit a common type of automobile wheel hub, the special features of which, in connection with my invention, relate only to thefasteningv of the disk to the hub. v.

- The web of the wheel is made ofa disk of metal which is thicker around the hub zone than it is on vthe -margin where it joins the rim, thus' having a tapering cross section from the central zone tothe rim. The disk is dished to a peculiar shape having a iiat `zone indicated by 2 located a little forward of the central load line of the wheel and around the hub zone and this at portion is merged into an offset swell indicated by 3 which extends farther outward in the front direction. The flat zone 2 is perforated for a series of screw studs 4iprovided with nuts le'yrhich the disk is secured to the hub and may be mounted or demounted as desired by unscrewing the nuts 5.

Outwardly beyond the flat zone 2 the disk is pressed inward to it the annular peripheral inclined surface of an inclined flange 7 of the hub, and this inclined-portion of the disk merges into an'annular swell 8 the outer portion of which is lcontinuous with a reversed swell 9 which is in turn integral with a third inwardly bent swell 10 continuous with an annular plane portion l1 having an inwardly extending marginal flange 12 fittino' against a rim member.

rivets 13 to a flange 14 of the main rim piece I and this method of securing the disk to the main rim piece is substantially the same throughout the several modifica-tions shown in the drawings, and the said modificatiom relate to the method of securing the Side ring of the rim to the main rim portion while the general yfeatures of the disk remain 'the same.

The disk shaped as indicated is very strong and serviceable and at the same time allows 1a sldight degree of elasticity under a rolling The flat zone 2 ofthe disk is so stiffened on each edge of this zone by the offset or swell 3 and the inclined surface 6, that no auxiliary .or secondary clamping ring is required under the nuts 5 of the screw 'studs 4,- which saves .the weight and cost of the auxiliary ring and also makes the wheel a little easier to clean.

The inclined pprtion 6, bearing on the innml reali clined lianes 'i' of the dish' fives on the cere tral load line a Wedging' union the dish'.

'and hub whereby the main general load car rying stresses are borne in the neutral central bearing point on the surface t5 and inclined n flange i and the lateral or slrid shoolrs are ,taken up over this bearing'point as a fuln crum working against the nuts 5 on the studs e. The shape of this hub zone of the disk, having they outward proj acting siv'ell or Harige 3 stiffens the edge of the hub aperture of the disk and transmits the load between the screws or Astuds ,4C to the studs themselves and thesame is true as relates to the inclined surface. 6. 'lhus the flatzone is stiffened on its margins which permits this zone to be used for the bearing surface of the nuts Without requiring any secondary flange v or clamping nuts for holding the dish to the hub.

i The studs et are prevented from being unscrewed by any suitable fastening means but I prefer to use a tapered pin 311 for this purpose.

Nut lool: rings, of the ordinary lock Washer type are seated on the inside of the heads "of the nuts 5 as indicated by 16 and bear directly on the heads ofthe studs 4e, thus serving to hold the nuts from accidentally coming loose.

l The wheel shown is for a rear Wheel of an automobile and the brake drum 17 is l screwed to the hub by bolts' 18 shown in the lower part of Figure 2 and in dotted lines in Figure l. However, this feature varies v with different makes of oars, but the arrangement of the hub connection Iwith the disk, may be adapted to almost any type of hub construction.

The preferred form* of rim is sho-Wn in Figures 4 and 5, wherein 19 is the main rim section which preferably is made out of a rolled special section, butis so formed that .with 4very slight modifications it may be made out of fiat stock. The side ring or detachable flange of the mainrim is injdicated by 2() in Figures 4 and 5 and this also preferably 'is a special section, but likewise may `be made out of flat stock by rounding olf the corners, as will be understood from ythe drawings. The main rim 19 is provided with a projecting flange 14:, as heretofore mentioned, and with a seat 21 upon which the side ring .flange 20 rests.

The main rim 19 is provided'with a series of slots or perforations 2 2 extending around f the inner edge of the surface 21 at intervals,

as will be noticed by Figures 3 and 6. y,

The side ring 20 is provided with a series of projections 23 as indicated by Figures t and i', which are adapted to lit into and register with the slots or perforations 22 of the main rim 19. The Way these projections 23- are made is tiret to provide a continuous dange on the side raap; 2U and then by a :rute

shearing1 operation\'eut awa-y this flange at to this, by having a side ring that is secured in place by means of a gutter and projections on the side ring which enter into this gutter by means of which the side rungl is held in place. .Y rll`he trouble with this type of rims is that While they may hold the tire I on securely and the side ring be easilyI removed and replaced, yet in removing the tire shoe the gutter portion on the main rim be-y comes a troublesome feature, as the tire beads spring down into the gutter and cause trouble in withdrawing the tire from the rim.. ln this Work with the type vof tires which have a gutter on the side of the side ring, the front side of the tire shoe or the bead portion on the outside may pass the gutter with some convenience, but the inside bead of the tirel shoe having a sharp and more or less flexible point or edge generally flexes down into the gutter as the shoe is beingrenioved, and causesa lot of Work and anno-yan'cein removinfr the ltire shoe `from that type `of a rim. lith the construction sho-W inthis application, there is no gutteron'the side, or features Which may clog the removing of the tire shoe from the rim and when the side ring -is taken out'there is ample clearance on the outside for the outside bead of the tire to be immediately free and there is a clear Way for the inside bead to slide od without catching anything and this is a great desideratum.

In Figure 8 the main rim piece19 is ina-dey out of a 'flat sheet of metal and is made a little Wider on the front edge vof the depend-y ing flange 14, as is indicated by the curved ortion 25. rllhus there is a full flatseat 'or the side rino' 2() and this side ring- 20` is shaped slightly different from those of Figures fand 5, 'by reason of the point 27 adapted to' lit more nearly the contour on the inside surface 'of the main rim 19, the

`projection 23 being substantially the saine as in Figures e and 5. y

ln Figures 11, 12and 13 il provide a different type cfa side ring and a slightly different section to the main rim portion and in these figuresll indicate'the side ring as 28 and the main rim portion as 19. ln this case the side ring is a special section rolled With a bead on the underside, which bead is mutilated, leaving the projections 29 which perform the saine function as the projections 23 heretofore mentioned.

The main rim in this instance is made out of fiat stock and is provided with same sort of a depending flange 14 as in Figures 4 and 5, but the rim is provided with a seriesl of perforations located near the front edge of the main rim 19, as is indicated by 30 in -Figure 16. In making these perforations the same results as Figures 4 and 5, but uses a slightly different location for the projections' on the side ring that interlock with the apertures, in the main rim. In Figures 14, 17 and 18, I make my vside ring out of'flat stock and indicate the side ring as 32 and in order to provide-the projections required for locking the ring in place on the main rim 19, I punch down some sections of the metal of the side ring into projecting points as indicated by 33 in Figures 14, 17 'and 18. Figure 17 is a cross section at intervals between these projections, while Figure 14 is a cross section through the projections. Figure 18 is a side elevation showing the 4appearance of the project-ions from the side. It is some times diflicult to get supplies of material of special rolled sections when Hat stock may readily be had and I provide this form, allowing the invention to be used and adapted to the type of material most easily obtainable at any given time. The results being substantially the same, save only with slight differences in cost, but I prefer to use the form shown in Figures 4 and 5.

In taking off a tire from my wheel with the rim, as indicated, which is always done `when the tire is deflated, the .tire is pushed inward oppositethe point 24, being the out asunder ends of the side ring, forcing the bead in beyond its bearing on the side ring at that point. Then, with a screw driver, or other suitable tool, the end of the side ring is sprung upward and outward, freeing the projections 23 onthe side ring 22 in the main rim at that end, whereupon the ring may be easily progressively sprung outward and removed almost inthe same manner-as the side rings are removed whereinside gutters are used.

What I claim is 1. In a wheel of the class described, a dished disk having its main bearing on the hub on the'central load line of the wheel and inclined thereon for a wedging action, with a zone on the said disk around the hub outward from the central load line through which extend fastening studs adapted to secure the disk to the hub and the inner edge of the said fastening zone having a bearing also on the hub.

2. In a wheel of the class described, the

combination with a hub having a peripheral face in the load plane of the wheel and inclined to that plane of a disk secured to the hub at a lessdistance than said face from the wheels aXis and dished to Inake contact with said face.

3. A wheel having a dished disk for the web and secured to a hub through the medium of a series of studs passing through a hub zone on the said disk and this hubzone stiifened on both edges' by swells in the body of the'disk adapted to help carry the load of fastening, uniformly around the hub zone without requiring extra stifl'ening flanges.

soY

4. In a wheelvof the class described, a

thereof; and having a zone around the hub adapted to aid in fastening the disk to the hub, said zone havingan inclined bearing seat adapted to seat on an incline face on the hub, and another bearing seat at the other edge of said zone adapted to seat on the said hub, with a clearance space between these seats where the disk and the hub do not come i i in contact.
